Inconel Nylon 625 lock nuts are ideal in many extreme applications, especially when vibration or shock loading makes nylon inserts necessary to reduce nut loosening.

Inconel 625 brings good corrosion resistance, high-temperature resistance, and ultimate tensile strength to a lock nut.

Made of nickel and chromium, Inconel 625 has high oxidation and carburization resistance. These lock nuts are resistant to a wide range of corrosive environments of unusual severity including sulfuric acid, hydrochloric acid, and phosphoric acid.

Inconel 625 Characteristics

Non-magnetic
Corrosion resistant
Oxidation resistant
Carburization resistant
Nickel-based alloy
Cryogenic to 2000°F temperature range
High corrosion-fatigue strength
High tensile strength

The molybdenum in Inconel 625 delivers excellent fatigue strength and resistance to stress, pitting and crevice corrosion cracking even when exposed to chloride ions making it an excellent choice for seawater applications. It is commonly used in submerged applications by the Navy on submarines and boats.
